my Toyota RAV4 XA50 (2019-2024) won’t shift gears what could be wrong

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and securely supported with jack stands.
• Disconnect the battery to prevent electrical shorts during inspection.

2. Check and Replace Transmission Fluid

• Remove the transmission dipstick and check fluid level. If low, add the manufacturer-recommended transmission fluid.
• If the fluid appears burnt or contaminated, proceed to drain and replace.
  • Tools Required: Socket set, transmission fluid pump, container for draining fluid.
  • Sub-steps:
    1. Place a container under the transmission pan to catch old fluid.
    2. Remove the transmission pan bolts using a socket.
    3. Carefully lower the pan and allow fluid to drain completely.
    4. Clean the pan and replace the filter if applicable.
    5. Reinstall the pan and refill with new transmission fluid through the dipstick tube.

3. Inspect and Repair Shift Linkage

• Inspect the gear shift linkage for proper alignment and condition.
  • Tools Required: Screwdriver set, pliers, and possibly replacement parts for damaged components.
  • Sub-steps:
    1. Locate the shift linkage assembly under the vehicle.
    2. Check for any loose or damaged connections.
    3. Tighten or replace components as necessary to ensure proper function.

4. Replace Brake Light Switch (if applicable)

• If the brake light switch is faulty, it may prevent shifting.
  • Tools Required: Socket set and possibly a flathead screwdriver.
  • Sub-steps:
    1. Locate the brake light switch near the brake pedal.
    2. Disconnect the electrical connector and remove the switch from its mounting.
    3. Install the new switch and reconnect the electrical connector.
    4. Test operation by ensuring the brake lights engage when the pedal is pressed.
